SHEET-METAL ROOFING.

Application filed March. 16, 1925. Serial No. 15,753.

This invention relates to improvements 1n corrugated sheet-metalroofing, and more particularly to the ridge roll construction 7 ofsuchroofing. V Corrugated sheet-metal roofing is made 1n sections andapplied to, the roof boards by starting at the gable end of the buildingand applyin the sections frornthe caves to the ridge o the roof, the ad-acent ends of the 10 sections overlapping acertain amount in the mannerwell known to those skilled in the with the corrugations of the adjacentends of the roof sections at the ridge, is then fitted over the ridgewith the flanges lapping over the adjacent ends of the corrugated roofsections. Considerable difiiculty has been experienced heretofore inarranging and securing the roof sections to the roof boards so that thecorrugations thereof will align with the corrugated flanges of the ridgeroll when the latter is fitted upon the ridge of the roof frame, thisbeing due to the fact that during the application of the sheets and thenailing thereof to the roof boards, there is some tendency for thesheets or sections to flatten out, which causes the corrugations tobecome out of alignment with the corrugations in the flanges of theridge roll. When the ridge roll is applied,

therefore, the corrugations of the flanges thereof will not properly fitor nest with the corrugations of the roof sections so that openings willoccur at the connection or joint between the flanges of the ridge rolland theadjacent edges or ends of the roof sections.

One object of the invention, therefore, is to provide an improvedcorrugated sheetmetal section of roofing which is so formed along one ofits ends as to form with an oppositely arranged and similarly formedsection, the'ridge roll for the roof, whereby the fitting together ofthese sections at the ridge with their respective corrugations in propernested relation is facilitated.

Another object is to provide complementary ridge roll forming flangesalong the ends of standard sized corrugated roof sections which may beapplied to the roofon either side of the ridge thereof, with the saidflanges overlapped so as to form the ridge roll without the difficultiesheretofore encountered.

Other objects will hereinafter appear.

In the drawings, Figure 1 is a side elevation, partly broken away, ofthe end of a roof, showing the manner in which the sheets or sectionsconstructed in accordance with the present invention are arranged andfitted together to form the ridge roll;

7 Figure 2 is a section on line 22 of Figure 1;

Figure 3 is a fragmentary perspective View of one of the improved ridgeroll members; and

, Figure 4 is a sectional view similar to Figure 2, showing a modifiedform. The roof sections 1 and 2 are applied to the roof boards 3 in theusual manner from the eaves to a point adjacent the ridge of the roof,the adjacent ends of the sections overlapping in the'well known manner.

According to the present invention it is proposed to provide the topsections 4 and 5 with complementary flanges adapted when said sectionsare applied to the roof, as shown in the drawings,'to inter-fit or nesttogether to form the ridge roll. The upper ends from the planes thereofand curved in substantially semi-cylindrical fashion, the upper end ofsection 5 fitting over or under the upper end of section 4, with therespective corrugations of these upper ends fitting together 1n nestedrelation. The upper curved of sheets or sections 4 and 5 are raised endsof the sections 4 and 5 thus form the ridge roll. This avoids thenecessity of employing a roll as heretofore, as well as the difiicultiesattendant upon such practice.

By reason of the semi-cylindrical configuration of the upper ends ofsections 4 and 5, which are nested together, as more clearly shown inFig. 2, there is only one seam or joint at 7 exposed to the elements.Water is prevented from enteringat 7, and leaking through the roof, byreason of the fact that the upper end of section 4 is nested under orover the upper end of section 5 and continues around in a semi-circle tothe other side of the ridge, as shown. No seam or connection occurs atthe opposite side of the ridge, for the reason that the upper curved endof section 5 is integral therewith.

As shown in Fig. at, a roof section 8 provided with corrugationsextending from end to end thereof may be raised adjacent end 9 of thesame to form a ridge roll 10, end .9 overlapping and nesting with theadjacent end of root section 11 and arranged at an angle. to theopposite end of section 8 equal substantially to the ridge angle.

Roof sections made in accordance with the presentinvention may be usedon roofs of any pitch. Various changes, of course, may be made withoutdeparting from the spirit of the invention or the scope of the claims.

The invention claimed is:

1. A sheet-metal roof section provided with corrugations extending fromend to end thereof, one of the ends of said section being raised fromthe plane thereof and shaped to fitand nestwith the raised end of asimilarly-formed and oppositely arranged section to form therewith aridge roll for a roof the other end of said section being adapted tooverlap and nest with the adjacent end of an ordinary corrugated sheetmetal roof section.

2. A sheet metal roof made up of corrugated sheet metal sections, thesections having their corrugations interfitling in the usual manner, theuppermost sections on both sides of the root having their upper endsraised from the plane of the uppermost sections and curved to form ridgeroll members, the ridge roll members having corrugations which arecontinuations of the corrugations of the main portions of the uppermostsections, the ridge roll members and their corrugations beingintcrlitted in assembly.

3. A sheet metal roof section which comprises a main portion corrugatedfrom end to end of such size and shape as to adapt it to consti ute oneof the uppermost sections of an ordinary corrugated roof and adapted tohave its lower end overlap and intertit with ordinary corrugated roofsections in the usual manner, and which is further characterized by theprovision at its upper end of a curved ridge roll member integral withthe main portion of the section and raised above the plane thereof, theridge roll member having corrugations which are continuations of thecorrugation of the main portion of? the section and are adapted to titand nest with a similarly formed ridge roll member on a similar thoughoppositely arranged section.

In witness whereof I hereto alfix my signature.
